Solar collector i.e. pass-through plate-shaped roofage collector, for heating air, has extruded substructure acting as spacers provided below collector, passed parallel to roofage collector and provided for undercurrent of absorber surface

摘要

The collector has an extruded substructure acting as spacers (32, 34) provided below a roofage collector. The substructure is passed parallel to the roofage collector and is provided for undercurrent of an absorber surface. The spacers form a flow through channel (36), where the spacers are arranged at a lower side of the collector. The substructure consists of wooden strips and plastic elements, which are provided for air turbulence. The substructure is formed from beveled perforated plate elements by which the air flow is swirled.
